At the moment, I am trying to make a project using GLFW, but I am getting a LNK2019 error for all glfw function. Most tutorials I seen involves using visual studio or CMake to setup the project, but finding a tutorial using the command line is hard to come by. On the bottom of the GLFW site about manual compilation, I do not really understand how it want me to setup the build (I still relatively new to building from command line). I am using Casey's build has the baseline for my GLFW build. I tried using /LIBPATH to tell the linker where it can find the glfw3.lib library, but still have errors. I also tried to mimic how visual studio setup GLFW, but came up with nothing. I also thought that the LNK 4272 warning was the issue and tried putting /machine:x86 on the linker, but that gave me an another problem.
Is it possible to link to glfw3.lib from command line? If so, how?
Workstation machine: Surface Pro 4 x64
Compiler: cl.exe x64
GLFW Download: 32-bit Windows binaries
My build file:
Error code:

This is compiler telling you that you are trying to link library which has 32-bit Intel x86 code with application that is compiled for 64-bit Intel x86_64 code. This is not supported. You are simply using wrong glfw library. Get the right one - for 64-bit builds.

Get the right one - for 64-bit builds.
Just tried using x64 glfw3.lib and got the same error code above.
However, I did switch the compilation from x64 to x86 on the x86 glfw3.lib and got a different set of error code. From that, I was able to add in the libraries I needed and got the glfw window to pop-up
Thanks for the help
